The one lesson I most want my students to learn is this: You can’t just say anything. It’s important to care about making sense. So I find it particularly galling when people violate this rule while presenting themselves to the public as economists. It undercuts the single most important lesson we have to teach.
THe latest culprit is the unchastened serial offender Robert Frank, writing in the Business section of the Sunday New York Times. His argument has two parts, one philosophical and one economic. In both cases he substitutes blather for analysis. I’m less concerned about the philosophical part, because it’s such obvious nonsense that I can’t imagine anyone will take it seriously. But the fact that he got the economics wrong, and more importantly, his implied message that it doesn’t matter whether you get the economics wrong, seems calculated to undermine the public’s faith in economists. That’s the part I take personally.
Frank’s subject this time is New York Mayor Bloomberg’s failed attempt to curb the sale of large sugary drinks. While acknowledging that such a ban would curb individual freedom in some dimensions, Frank argues that it would simultaneously enhance individual freedom in others — namely, it would enhance your “freedom” to prevent your child from drinking lots of soda.
Now, I do not doubt that for some parents, a ban on large sugary drinks would make it easier to prevent children from drinking lots of soda, but to call this an enhancement of freedom, you (or Robert Frank) would have to use the word “freedom” in a very unorthodox way. By Frank’s definition, a ban on Democratic campaign ads would enhance your “freedom” to prevent your children from voting for Democrats. Would Frank endorse such terminology? Or suggest that this effect, in and of itself, might suffice to consider the advertising ban a generally pro-freedom initiative?
